Sialography

Sialography

The disease of the salivary glands they would inject contrast in order to be able to kind of see because at the site the salivary glands don't show up on a regular x-ray and so you have to get some contrast in there and a lot of times they use just a tiny little amount of oil-based contrast.

The parotid is the submandibular also called the submaxillary and then the sublingual and these glands.

Indications:


Detection of calculi, foreign body

Detect the extent of destruction of the gland

Detection of fistulae and strictures

Diagnosis swelling and inflammation

Demonstration of tumor

Selection of biopsy site

 Stones in saliva glands there could be strictures which that's anytime you've got one of these ducts that are being clamped off by either deposition of some kind of detritus in the gland you know this is causing it to get narrower or there could be a growth near the gland that's cutting it off and what would happen here is that somebody would have a lot of like really really dry mouth or pain in their pain and their jaws coming from these glands.

Contraindications

Iodine compound sensitivity know to the patient

During acute Inflammation

 Preparation for this study

HMP history and physiology always you know and ask the patient why we're doing the exam if they've got any removable dental work you know false teeth or whatever and then let the patient know.

Contrast Medium used for sialography

Lipid soluble(Ethidol)

Non-Lipid soluble (Sinografin)

Steps in sialography

Scout Film

Parenchymal phase

Filling Phase

Evacuation phase

Scout radiographs and we would do like uh normally we would do like a slight

oblique and then a lateral with tight collimation just to see if there's any stones or any cause for concern there before the dodger would go in and actually start doing start probing around for these glands and that's this business right here the sigh oh silo with Isis, that's a stone.

we get the patient this lemon juice to suck on and that helps dilate these ducts and really get their saliva flowing.

Equipment for Sialography

Polyethylene tubing with a special blunted metallic tip with side holes for the salivary gland.

A similar tubing for injecting the submandibular gland has an end terminal end hole.

A 5 to 10 cc syringe

Lacrimal dilators

Contrast medium Ethidol or Sinografin

Lemon extract in the plastic container

Technique

The filming procedure in sialography is done when the patient is in the Supine position

All dentures should be removed

3 to 4 sts of films are obtained during the entire procedure.

To avoid superimposition of the mandible on the parotid gland Open mouth

Additional Views

Reverse basilar view

For the deep portion of the Parotid gland

Occlusal View

Subtraction View for diner ducts

Complications not many we could we can always cause an infection you know

because it's just the nature of our business oily contrast can possibly cause granulomatous reactions especially in people with Sjogren's disease which is an autoimmune disease that causes the salivary glands to enlarge and malfunction.

Hysterosalpingogram (HSG)

Image
 The hysterosalpingogram or HSG is a simple x-ray procedure performed using fluoroscopy with intermittent still images for documentation in general the actual procedure takes three to five minutes the hsg is a relatively low-risk procedure but does result in ovarian radiation exposure greater than a pelvic CT scan thus repetitive 8 sets hsg procedures should be avoided and the radiation exposure time  Demonstrates performance of an HSG notice the slow filling of the uterine cavity with radio-opaque dye while the uterus is positioned perpendicular to the x-ray beam subsequent fill of the fallopian tubes are visualized with a free spill into the peritoneal cavity unfortunately many women have preconceptions that the HSG is a very painful test there is no question that the discomfort is influenced by the experience of the operator an HSG is performed with the installation of a radio-opaque contrast into the uterine cavity installation devices include instruments that fit into the cervix s

Percutaneous Transhepatic Cholangiography ( PTC )

Image
 Percutaneous Transhepatic Cholangiography ( PTC ) PTC is an x-ray procedure that involves direct-inject of contrast medium in the bile duct. These are the ducts that carry bile from the liver to the gallbladder and small intestine In this procedure, a thin needle is directly inserted through the skin into the liver to reach the bile duct. Indications Contraindication Equipment Patient Preparation Procedure Aftercare Complication                 Indications ERCP procedure is failed  Strictures in the bile duct Suspected bile duct obstruction Billary system delineation in the presence of intra and extrahepatic biliary calculi Cause of Jaundice Suspected tumor Anatomic evaluation of complications of ERCP                     Contraindications Suspected pregnancy Allergic to contrast medium Bleeding tendency Gross Ascites - Fluid in the abdominal cavity Sever infection at the puncture site Chronic liver disease Billary tract sepsis            Equipment Fluoroscopic unit with spot film ligh

Ultrasound for Aorta

Image
 Ultrasound of the aorta The anatomy of the abdominal aorta runs from the aortic hiritis to the bifurcation it has three major anterior branches the celiac axis at t12 the sma at l1 the ima at l2 it has multiple paired branches of which the most significant is the renal arteries at t2 the gonadal arteries and there are four paired lumber arteries this these are the gonadal arteries the celiac artery and the sma arise from the anterior aspect of the proximal aorta, this is the select axis and this is the sma in one to three percent of patients the celiac artery and the sma arise from a common trunk this is the common trunk coming off here and giving off the celiac.  Aorta technique The abdominal aorta technique measures the aorta and common iliac arteries from the outer diameter in the ap and transverse planes. Doppler tips Doppler tips aliasing is a marker of stenosis the doppler spectrum should be obtained from the site of aliasing or turbulent flow in this case from the origin of the
